Function for visualisation of raw data -Ovarian cancer

I want to a 'plot' function to effectively visualise the ovarian cancer data inbuilt in MATLAB.
load ("OvanrianCancer.mat")
The variable X (a 4000 by 216 matrix containing 4000 gene expression from 216 patients with and without ovarian cancer) is what I want to visualisation in its raw form to get an insight of its patterns. I intend to use a modal decomposition algorithm to analyse and re-construct it.
I have tried different 'plot' function but the results are awlful. I guess it's me not using the right 'syntax' or commands.

Try this:
load('OvarianCancer.mat')
plot(X, '-');
grid on;
Do you want to make a model of it? Do you have any ground truth for the data?

You have over 800000 data points of floating point values that you are asking to draw in a single graph that probably is only about 1000 pixels + borders wide. It is not obvious to me that you can have any possible meaningful visualization — not unless you are doing some kind of summary like histogram.
